I don't think my daughter will cough up a grand on a saw, BS. She got a Ryobi two years ago and it's rubbish. I think she will pay up to £350-00 for a decent one.
When you are after a Stihl with a 25" bar .. £350 just wont do it. I'm afraid you will need to lower your sights or raise your budget. Here's a bargain for you .. http://tinyurl.com/nd2lz89
Stihl and Husqvarna are the two top notch brands used by professionals, plenty of other makes out there for occasional use but are usually less powerful.
I find a Stihl with a 16" bar suitable for most jobs. Its a serious piece of kit!
